Abstract

Right (R)- and left (L)-handed helical G-quartet nanostructures were synthesized for the first time simultaneously via the self-assembly of 5'-guanosine monophosphate (GMP), the helical handedness of which is well regulated by metal ions. These g-nanostructures were further applied as circularly polarized luminescence (CPL) templates to realize full-color R-/L-CPL and Förster resonance energy transfer CPL. The glum value reached 10-2, indicating their excellent template function for CPL materials design and application.

摘要

首次通过 5'-单磷酸鸟苷（GMP）的自组装同时合成了右手（R）和左手（L）螺旋 G-四联体纳米结构，其螺旋手性由金属离子很好地调节。这些 g-纳米结构进一步用作圆偏振发光（CPL）模板，以实现全彩色 R-/L-CPL 和Förster 共振能量转移 CPL。glum 值达到 10-2，表明它们对 CPL 材料设计和应用具有出色的模板功能。
